1. Field of the Invention

The present invention relates to a human body cooling apparatus, and particularly to a human body cooling apparatus light-weighted and adapted to utilize a cooling effect of a cooling medium containing gel so that the human body cooling apparatus is preferably usable to exemplarily cool portions of a human body.

2. Description of the Related Art

Conventionally, people has accommodated a cooling medium containing gel in an exterior element of a pillow size or a bed sheet size to form a human body cooling apparatus, and at the time of sleeping, or the like, in a high temperature season such as a summer season, has covered the human body cooling apparatus onto a pillow to thereby cool a head of a human body, or placed the human body cooling apparatus on a bed to thereby cool a back, and the like, of the human body.

In case of such a human body cooling apparatus where the same is used instead of a covering futon, for example, the human body cooling apparatus is required to be light-weighted and flexible in addition to possession of a cooling effect, so as to obtain a good feeling upon use.

Further, with such a human body cooling apparatus, the migratability of a cooling medium containing gel accommodated inside the apparatus is high, thus if the cooling medium is simply accommodated in the exterior element, the weight of a human body would cause the cooling medium to be unevenly distributed within the exterior element, resulting in failure of expectation of a sufficient cooling effect for the human body.

The present applicant has proposed a human body cooling apparatus having an excellent cooling effect for a human body at the time of sleeping, or the like as shown in Patent Document 1, and has obtained an utility model registration based thereon, where the human body cooling apparatus is configured to comprise: an exterior element in which two covering members in the shape of a rectangular seat each having a front cloth and a backing cloth are put one upon another with the backing cloths being superposed on each other to provide a flat form, the backing cloths being high-frequency welded for formation of an outer edge welded portion, a toric partially welded portion having an air bleeder hole for heat radiation in a plurality of places in an internal area thereof, and straight-linear middle welded portions; and a cooling medium containing gel accommodated in the exterior element such that migration thereof is restricted by the outer edge welded portion, partially welded portions in the internal area thereof, and middle welded portions.
